The aim of this study was to determine the effect of different ratios Cr particle reinforcement on the hardness and wear resistance of Cu matrix composites produced by using (P/M) method. Cr particles were added at different weight ratios of 5, 10 and 15%, in pure Cu dust. The prepared mixtures were shaped under a pressure of 400 MPa. The shaped pieces were sintered at 900 °C for 30 min. The success...
Structuring has been examined for Cr-Cu composites under conditions of impregnation and subsequent liquid-phase sintering at 1200°C in a vacuum of (2–4) · 10−3 Pa with reduced and electrolytic chromium powders. The size distribution for the particles of the refractory component in the microstructure containing the reduced chromium on liquid-phase sintering for 60 min corresponds to a logarithmic normal...
